In theaters now is "Free State of Jones", based on a confederate rebellion in southeast Mississippi and starring Matthew McConaughey.

Also in the big budget release are Brandon Elementary twins, Camden and Carsen Flowers. The young faces are practically old pros at acting. In fact, the film's casting director contacted them to offer the featured roles.

Matthew McConaughey filmed for four days with the Flowers twins.

The story is about Newt Knight, a Jones County Confederate defector, who gathered a band of rebels to fend off the army's possession of the property of poor soldiers. The 10-year-olds portray the daughters who Knight arms and trains.

"He came up to us and started talking to us about the character and what we thought we would be like and he stayed in character a lot, and he never really got out of character," said Camden Flowers.

"We were supposed to be really scared because these people were coming and they were taking our stuff and they said we're gonna take 10 percent but yet it was really like they just left 10%," said Carsen, who is 30 seconds younger.

The girls have seven film credits and have been acting for nearly four years. They were ecstatic about working with McConaughey in a story based on Mississippi history.

"He's such a big name and a big face that you're there and you're just kind of like 'Oh gosh what do I do next,"' added Camden.

"I didn't know it was a true story until I looked at the poster that it was it a true story," added Carsen. "And when I heard it was a true story I was like 'Wow'."

They filmed in Covington, Louisiana, last March and saw it for the first time on Tuesday.

"Of course I thought that was the best scene in the entire film," said proud mom Mandye Flowers.

She and husband Anthony said the kids begged to begin auditioning after hearing a radio promo and reviewed and researched the scripts and roles.

"They're able to do this and get money toward their college and be seen in these big budget movies and just have a blast," said Anthony, who often accompanies the children on set. "So this is the age we're living in, all this technology out there. We video auditions and send then off and book these huge roles."

Camden and Carsen aren't the only ones in the family with SAG cards. Big brother Aiden has appeared in nearly 20 feature films.
